[Image-SIG] PIL Compile Error Mac 10.5.4

[Adrian Price-Whelan]

Hey -

Having an issue building PIL on my intel Macbook Pro running 10.5.4.:

ld: in /sw/lib/libxml2.2.dylib, file is not of required architecture  
for architecture ppc
collect2: ld returned 1 exit status
lipo: can't open input file: /var/folders/U8/U8oYQjnOFIi8el0mQQiHaU++ 
+TI/-Tmp-//ccZZXwfx.out (No such file or directory)
error: command 'gcc' failed with exit status 1

Not quite sure whats going on with this...any help would be much  
appreciated. Thanks!
